WHAT IT DOES

What CreateAHORunCache does on Amazon MQ MCP Server

WHY IT NEEDS A POLICY

Why CreateAHORunCache needs a policy

The 'Create' prefix in the tool name indicates a write operation that establishes a new resource (a cache). This is reversible (can be deleted) and has moderate blast radius if misused by an AI agent—it could provision unwanted cache infrastructure, consuming resources or creating security exposure.

From the tool's definition Tool name 'CreateAHORunCache' suggests creating or provisioning a cache resource. The 'Create' prefix indicates a write operation that generates new data/resources. Description is empty, which limits certainty.
